The Antilles Sea is an expansive body of water on Ord Mantell. The city of New Alderaan rests on the southwestern edge of the sea, nestled around a natural inlet. The inlet itself was created many millenia ago, when a large asteroid plummeted into the terrain. Centuries later, the neighboring body of water would fill the inlet, lowering the overall sea level and helping to create some of the expansive plains bordering the New Alderaan wilderness.
